My use case is a homelab kubernetes cluster, so I want multiple nodes for redundancy, but I don’t want to use too much electricity or generate too much heat. But for the sake of other readers, let’s keep it general:
What’s a nice little computer for a homelab, with its own power supply, ethernet, and room for 2 internal disks?
They’re not energy efficient when they’re working, but usually servers are idle 95% of the time.
You’ll spend more money buying new hardware than the power you save.
